Proud of myself

Today might be one and only time in my life that I will be able to say this: I did something that was more 'thinking like an economist' than Steven Levitt! On the Freakonomics blog this morning, Levitt wrote about how he and his family dealt with a problem with their cat. Unfortunately, their solution to the problem involved doing several different things, any one of which might be the true solution. Since some of the things involve substantial cost (like kitty Prozac - I kid you not, go read it!), it would be good to know what was the real key so they could stop the other things. Levitt uses this as a lesson in the benefits of experimentation. He's basically advocating putting 'ceteris paribus' (all else equal) into action - i.e., keeping everything the same while you change one thing at a time, so you can isolate what works and what doesn't (and I assume this is how they will eventually figure out what they can subtract from their cat's regimen).

So the reason I'm proud of myself is that I actually went through this exact thought process earlier this week. I've always gotten occasional pimples, but for some reason, I've been breaking out more in the past few weeks (and since it's summer, I definitely can't blame it on stress). So I was at Target, about to buy new facial cleanser, some pimple cream and a stronger exfolliant, when it occured to me that I should only try one thing at a time so I could figure out exactly what was working (though probably the main reason this occured to me is that I was trying to figure out how to not have to stop eating chocolate as well but that's not the point...). So when I read Levitt's post, I knew exactly what he was talking about. I just can't believe it didn't occur to him until after they had made all the changes for the cat...

What are the costs?

I came across an interesting discussion about a 19-year-old intern who was fired from The Gazette in Colorado Springs for plagiarism. There appears to be some controversy over the fact that the editor publicly named the girl in a letter to readers (explaining and apologizing for the plagiarism), with some people saying that doing so was unduly harsh because this incident will now follow her for the rest of her career. I was intrigued by this discussion for two reasons - one, it seems pretty clear to me that this was not a case of ignorance (as I have often encountered with my own students who have no idea how to paraphrase or cite correctly) and two, putting aside the offense itself, I have often struggled with how to handle situations where there are long-term repercussions for a student, repercussions that lead the overall costs to be far higher than might seem warranted for the specific situation. As an example of the latter issue, I have occasionally taught seniors who need to p

What was your high school economics experience like?

As I mentioned in my last post , I am asking my Econ for Teachers students to reflect on their reading by responding to discussion prompts. It occurred to me that it wouldn't be a bad idea for me to share my thoughts on those issues here and see if anyone wants to chime in. For this week, the students were asked to read the California and national content standards , an article by Mark Schug and others about why social science teachers dread teaching economics and how to overcome the dread, an article by William Walstad on the importance of economics for understanding the world around us and making better personal decisions (with some evidence on the dismal state of economic literacy in this country), and another article by Walstad on the status of economic education in high schools (full citations below). The reflection prompt asks the students to then answer the following questions: What was your high school econ experience like? What do you remember most from that class? How do

When is an exam "too hard"?

By now, you may have heard about the biology professor at Louisiana State (Baton Rouge) who was removed from teaching an intro course where "more than 90 percent of the students... were failing or had dropped the class." The majority of the comments on the Inside Higher Ed story about it are supportive of the professor, particularly given that it seems like the administration did not even talk to her about the situation before acting. I tend to fall in the "there's got to be more to the story so I'll reserve judgment" camp but the story definitely struck a nerve with me, partly because I recently spent 30 minutes "debating" with a student about whether the last midterm was "too hard" and the whole conversation was super-frustrating. To give some background: I give three midterms and a cumulative final, plus have clicker points and Aplia assignments that make up about 20% of the final grade. I do not curve individual exams but will cu
